1 Claim.

This invention relates to new and useful iniprovements in what is generally known as clam shell buckets.

The principal object of the present invention is to provide a bucket of this character which will actually dig into the material being handled instead of scraping along the top thereof as occurs with present day types of buckets.

Another important object of the invention is to provide a bucket which is constructed in such a manner as to be capable of actually cleaning a surface of all material to be loaded.

Still another important object of the invention is to provide a clam shell bucket which because of its sturdy construction will not be susceptible to the ready development of frequent defects.

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a side elevational view of the bucket with the shell sections in vertical section;

Figure 2 is a side elevational View of the assembly with the shell sections in open position;

Figure 3 is a back elevation of the assembly;

Figure 4 is a fragmentary vertical sectional View on line ii of Figure 1;

Figure 5 is a top plan view of the frame; Figure 6 is an enlarged vertical section on line 6 of Figure 3;

Figure 7 is a top plan view of the slider; Figure 8 is a section on line 88 of Figure 1. Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents the hoist frame consisting of the vertical side members 5-5 and the cross straps l-'! connecting the upper ends thereof. Mounted between the straps 1l are the rollers 8-8 while upon the straps l--l are the cross members 9-9 between which a plurality of rollers I6 are mounted. The cables H-IZ pass between these rollers 8-i0, the rollers serving as antifrictional means.

An elongated pin or shaft I3 extends through the lower portions of the frame members 6-S and this shaft I3 extends through the apices of the side walls M of the clam shell sections i5l5, and on one of these sections !5 eye members if) 50 can be provided and to which cables can be attached for steering the bucket while the same is in operation.

A pair of plates l7-l7 have their ends secured to the side members 6-6 at the lower portions 55 thereof, and between these plates l'l-l'i is the cage I8 in which the pulleys 920 are mounted.

As shown in Figures 3, 4, and 7, numeral 2! represents the slider which consists of the plates 22-32 spaced apart by the blocks 23-23, leaving end portions 2 5 for disposition over opposite side portions of the side members 66 of the frame 5. Within the slider 2! is mounted the plate member 25 which at one end is provided with the eye 26 to which the lift cable H is secured. The other end of the plate 23 has the shaft 21 of the pulley 28 disposed therethrough, this pulley 28 overlying the pulleys l92l.

The cable l2 which controls the sections of the bucket extends downwardly under the pulley it and then up over the pulley 26, and then downwardly under the pulley 28 from where it extends to be anchored, as at 29, to one of the plates ii. It is of course to be understood that any other form of block and tackle can be employed, depending upon the character of work to be executed with this bucket.

Ears an arranged in pairs on the outsides of the plate H have the upper ends of the links 38 pivotally connected thereto, while the lower ends of the links 3! are pivotally connected to ears 32 on the bucket sections 15-!5.

It can now be seen that with the sections of the bucket open in the manner shown in Figure 2, the assembly is lowered by the cable H into the material to be loaded and when it reaches the material, the lift cable H is released and pull is then exerted on the bucket cable l2. This pull on the cable i2 causes a downward movement of the slider 20 on the frame 5 and this motion imparted by way of the links it will cause contraction of the bucket sections i5 as they make a sweep through the material under the weight of the entire assembly. In this manner an actual digging into the material is executed by the bucket sections instead of a mere scraping operation which generally occurs with most types of buckets.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

A bucket assembly of the character described comprising a frame provided with a slider thereon and having side portions, a pair of bucket sections pivotally mounted on the frame, a lift cable connected to the slider, a bucket controlat the end of the slider and an intermediate passageway for the disposition of the cables, the end portions of the said plates overlapping the side portions of the frame, and pivotal link members between the slider sections and the bucket sections.
